U.S.A., a corporation of Pennsylvania Filed Nov. 17, 1965, Ser. No. 508,284 9 Claims. (Cl. 52-616) ABSTRACT F THE DISCLOSURE Multiple pane window units in which tubular spacers are provided between the panes with pockets in side walls of the spacers for sealing material and sockets in outer walls of the spacers. Clips are provided engaging inthe sockets and either with the face of a glass sheet or with another socket.

This invention relates to multiple pane window units, that is to heat insulating window units composed of a plurality of glass sheets separated from each other at their edges by spacers and retained in position by metal clips along their edges.

The principal object of the pre-sent invention is to provide improved spacers for multiple pane window units that cushion shock and effectively seal and separate the edges of the window units.

' A further object of the present invention is to provide improved retaining and gripping appartus for multiple pane window units.

A further object of the present invention is to provide improved retaining clips for multiple pane window units that are suitable for use on units with varying numbers of glass sheets.

A further object of the present invention is to provide a structure of the character aforesaid that is simple and inexpensive to manufacture but sturdy and reliable in use.

Other objects and advantageous features of the invention will be apparent from the description and claims.

The nature and characteristic features of the invention will be more readily understood from the following description taken in connection with the accompanying drawing forming part thereof, in which:

FIGURE 1 isa fragmentary front view of a portion of a Window unit in accordance with the invention;

FIG. 2 is a viewv in perspective of a portion of a spacer in accordance with the invention;

FIG. 3 is a vertical sectional view taken on the line 3-3 of FIG. 1;

FIG. 4 is a view similar to FIG. 3 showing a modified form of the invention;

FIG. 5 is a view in perspective showing a corner retaining clip for use with the window unit of the present invention; Y v

FIG. 6 is a view in perspective showing a side retaining clip for use `with the window unit of the present invention;

FIG. 7 is a viewsirnilar to FIG. 6 showing another form of retaining clip; and

FIG. 8 is a view similar to FIG. 7 showing another form of retaining clip.

It should, of course, be understood that the description Iand drawings herein are illustrative merely, and that various modifications and changes can be -made in the structure disclosed without departing from the spirit of the invention.

Like numerals refer to like parts throughout the several views.

Referring now more particularly to the drawings in which a preferred embodiment of the invention is illustrated, the multiple pane window units there shown in- ICC clude la plurality of sheets or panes of glass 8 having opposite side faces 9 and terminal edges 10, held in spaced relationship by spacers 11 and retained together by clips 12.

The spacers 11 are preferably formed of sheet metal, but other suitable material can be used, and are of cornplex shape as shown more particularly in FIGS. 2, 3 and 4. These spacers 11 are initially formed to necessary dimension requirements, and fitted together at the corners so as to form aninternally isolated `box like perimeter structure along the edges of the panes 8. Each one of thespacers 11 is of generally rectangular shape in cross section as shown in FIGS. 2, 3 and 4. 4

The structure of the spacers 11 as can be seen particularly in FIGS. 2, 3 and 4, includes a side wall having a fiat portion 14 which in assembled position engages a face 9 of one of the sheets of glass 8. An inwardly extending portion 17 of V-shape in cross section is provided contiguous to the lower edge of the portion 14 forming a pocket 15 thereby for the reception of sealing and shock absorbing material 13. A fiat wall strip 16 is integrally connected to the V-shaped portion V17.

The wall portion 14 has perpendicular thereto and integral therewith an outer wail portion 18 from which an interior-ly disposed wall portion 20 extends to provide a longitudinal socket 21 isolated from the interior and with a throat 21a of lesser width than that of the interior of the socket 21.

The spacer 11 is preferably symmetrical about a central longitudinal plane and has a wall portion 20 forming the other side boundary of the socket 21.

The spacer 11 has another w-all portion 18 in coplanar relation to the first mentioned wall portion 18, another wall portion 14 parallel to the first mentioned wall portion 14, an opposite inwardly extending V-shaped portion 17 forming an opposite pocket 15, and another flat w-all strip 16 in the same plane as the other wall strip 16. The wall strips 16 have serrated meeting edges 19.

The retaining clips 12 are of various forms to accommodate the desired number of glass sheets 8 used to make a Imultiple pane unit. The clip 12, as shown in FIG. 5, is a corner clip comprised of fiat central strips 23 and 24 at a 90 angle to each other with struck out tongues 26 at the center thereof which extend into the sockets 21. The strips 23 and 24 have bent edge walls 27 fastened thereto and disposed at an acute angle to press inwardly on the faces 9 of the glass sheets 8 `with which they engage and retain them in assembled position.

The clip 12a, as shown in FIG. 6 is similar to the clip 12 of FIG. S and has a fiat central strip 28 which is adapted to be placed along the edges 10 of the sheets 8 as desired and has bent edge walls 29 at acute angles to the central strip 28 to provide a spring action in engagement with faces 9 of the sheets 8. The retention of two sheets 8 of glass in a dual sheet window unit by such clips is shown in FIG. 3.

In order to prevent the accidental disengagement of the clips 12a the tongues 26 can have extending therefrom locking fingers 30 which can be readily entered through the throat 21a by reason of the resilience of the fingers 30 but engage one of the wall portions 20 of the socket 21.

The clip 12b, as shown in FIG. 7, is substantially one half of the clip 12a of FIG. 6 and can be used on the outside sheet of the multiple pane unit when more than two sheets of glass 8 are used. The clip 12b has a central strip 28 with one bent edge wall 27 and with tongues 26 along its other side edge. The tongues 26 preferably have locking fingers 30 as before.

In FIG. 8 another clip 12C is shown which comprises a fiat strip 31 with tongues 32 on each side thereof extending out of the plane of the strip 31 longitudinally spaced as desired. The clip 12C of a width to permit it to bridge one sheet 8 of glass and a full spacer 11 is used to retain the intermediate sheets of glass 8 in assembled position when more than two sheets 8 of glass are used.

The assembled multiple pane unit of FIG. 3 comprises two sheets 8 of glass with a spacer 11 interposed therebetween, sealing material 13 lling the V-shaped indentation 15 and clips 12 -and 12b as shown in FIGS. 5 and 6, holding the edges of the glass sheets 8 in assembled relation.

In FIG. 4 a multiple pane unit is illustrated having more than two sheets 8 of glass and utilizes the clips 12b and 12 as shown in FIGS. 7 and 8.

With the foregoing in view the mode of assembly will now be pointed out. The spacers 11 Iand sheets 8 of glass are cut to suitable size as desired. The spacers 11 are placed between the sheets of glass 8 at their outside edges. The V-shaped pockets 15 are then filled with the shock absorbent adhesive sealing material 13 as desired. The clips 12a -are installed over the edges 10 of the glass sheets 8 with the tongues 26 extending into the clip receiving socket 21 and the edge walls 27 pressing on the faces 9 of the glass sheets 8. When a multiple pane unit of more than two sheets 8 of glass is desired the clips 12b and 12e can be used. The clips 12b have one edge wall 27 pressing on the outer face 9 of the outside sheet 8 of glass and the tongue 26 extending into the pocket 21 of the spacer 11. The intermediate sheets 8 of gl-ass are urged together by the clips 12C with tongues 32 extending into the sockets 21 of the spacer 11 bridging a sheet 8 and engaging contiguous spacers 11.
